AIR-HEATING- STOVE.

I Specification of Letters Patelit No. 2,556, dated April 16, 1842.

To aZZ whom it may concern:

Be it known that I, SALVIN F. KnLLooc, of Norwalk, in the county ofHuron and State of Ohio, have invented an Improvement in the Manner ofConstructing an Air- Heating Stove, for the WVarming of Apartments; andI do hereby declare that the following is a full and exact descriptionthereof.

In my air heating stove, the air that is to be warmed, and subsequentlyconveyed Wherever it may be required, is to be conducted to the heatingapparatus through a suitable tube, from any source of pure air withoutthe apartment in which the stove is situated.

The apparatus for heating the air con sists of air fines, or channels,contained within the stove immediately above the fire chamber; on itslower side, it is exposed to the direct action of the burning fuel, and

over its upper side the currentof heated air from the fire passes in itsWay to the smoke, or exit, pipe. The cool air that is admitted throughthe conducting pipe, passes back and forth between three plates ofcast-iron, which constitute the air fines, and which extend across thestove from side to side, and it is thence cohveyed, by means of asuitable pipe, or pipes, wherever it may be required.

In the accompanying drawings, Figure 1, is a perspective view of mystove, and Fig.

2, a vertical section through the middle thereof, from front to back.

A, is the fire chamber for containing the wood, or other fuel.

B, B, are the air-heating chambers, or

flues, which consist of three horizontal plates,

and side plates of cast iron, forming an inclosed box; the upper plateC, of this box extends from side to side of the stove. side and endplates D, D, slope from the top to the lower plate E, so as to exposesaid sides the more perfectly to the action of the fire.

F, is a conducting pipe through which the external, cool air is to beconveyed into the lower section of the air-heating chamber, as at F. Themiddle horizontal plate G,

serves to divide this chamber into two compartments, and to cause theair to pass toward the front of the stove and thence back toward thepipe, or tube, H, through Its which the heated air is to be conveyedwherever it may be required; its course w1thin the air chamber isindicated by the arrows a, a.

I, is the smoke, or exit, pipe, in passing to which the smoke and heatedgases from the fire observe the course indicated by the arrows b, b. i

To supply the requisite quantity of moisture to the heated air, as wellas for other purposes, I employ a large boiler J, which is closelyfitted to a boiler hole in the top plate of the stove; and from theupper part of this boiler two tubes 0, and (Z, lead into the air andsmoke pipes H, and I. In each of these tubes there is a valve e, e", bywhich the passage of steam to either of those pipes may be regulated andgoverned. The lid of this boiler is to fit closely, like that of adigester, and is to be furnished with a valve as at f. By thisarrangement any desired quantity of vapor may be passed into the heatedair pipe H; or it may be allowed to escape into the stove room throughthe valve f, or into the smoke pipe through the tube 0. In forming myair-heating chamber, I cast the bottom plate E, and the sides in onepiece, providing suitable ledges for the plate C, and G, to rest upon,and these I secure in place by means of fire clay, or other suitablecement, so as to render the joinings air-tight; this being essential tothe proper action of the instrument.

Having thus, fully described the construction of my air-heating stove,and shown the manner in which the same operates, I do hereby declarethat I do not claim the conducting of cold air into an air-heater to bewarmed, nor the subsequent conveying of the air so heated to distantapartments, this having been frequently effected, and by means ofapparatus constructed in a variety of ways; but I limit my claim to theparticular manner herein described, in which I have combined andarranged the stove, the air-heating chambers, or fines. and the boiler,with their appendages, as above set forth; that is to say,

I claim- 1. The manner of forming the air-heating chamber, or flue, B,B, and of arranging it within the stove, so as to occupy the whole widththereof, and to have its upper and lower plates, and its sides, exposedto the valves, in the manner, and for the purpose, direct action of thefire, or to thlat of the above set forth. heated air immediatel esca ingtier-e rom.

2. I claim, also, the nailingof combining KELLOGG' 5 the boiler, theheated-air pipe H, and the Witnesses:

smoke pipe I, by tubes leading into each, Tnos. P. JONES, the respectiveparts being governed by M. J ONES.
